Network configuration guidelines

Switch features and configurations vary between manufacturers. Refer to the manufacturer's user manual when configuring the required features to support MoIP.

Caution: Configure the network before connecting MoIP devices to avoid network flooding and overall instability.

  • Core Network Switch — The backbone of your local area network. This switch connects directly to your router and all other switches connect to this switch.

  • Edge Network Switch — A switch connected to your Core Network switch.

  • Core MoIP (IGMP) Switch — This is where your MoIP network starts. Think of it as its own topology within the larger network, dedicated to the MoIP.

  • Edge MoIP (IGMP) Switch — A switch connected to your Core MoIP switch.

  • IGMP Snooping — This switch function listens for Internet Group Management Protocol (IGMP) messages to create an internal list of what devices have requested which IP multicast transmissions to be forwarded to them.

  • IGMP Snooping Querier — Periodically requests all client devices on the network to report in with the multicast groups they wish to be joined with, to make sure that the IGMP snooping groups are updated to prevent multicast traffic loss.

  • Multicast Routing — The forwarding of multicast traffic between segments of a network. Primarily VLANs and the LAN.

  • Unregistered Multicast — Multicast traffic sent across a network that has had no IGMP messages associated with it. A network switch can decide to continue flooding this traffic through the network or to drop this traffic until an IGMP message has been seen for that multicast group.

  • Fast Leave — A network switch function that causes a port to act on an IGMP leave message to remove the associated multicast group from the port without waiting for the normal leave to expire.

    Caution: Do not enable Fast Leave on ports connected to the MoIP controller or uplinks to other switches.

    Read Understanding Multicast & IGMP to learn more.

You must apply the following settings to all the managed switches in the network: 

  • IGMP snooping must be enabled and set to v2. 

  • Unregistered multicast behavior set to drop.

  • MRouter/Router Auto-learn enabled.

  • Fast Leave enabled on Araknis 920 switchports connected to B-960 devices. This does not include switch uplinks or the MoIP controller.

  • The core MoIP switch must have IGMP Querier state enabled and set to v2.

  • Edge switches must have the IGMP Querier state disabled.
